Welcome to the O’Reilly Automotive Incorporated second quarter earnings release conference call. My name is John, and I will be your operator for today’s call. At this time, all participants are in listen-only mode. Later, we will conduct a 30-minute question-and-answer session. Please note this conference is being recorded. I’ll now turn the call over to Mr. Tom McFall. You may begin.
Thank you, John. Good morning, everyone, and thank you for joining us. During today’s conference call, we will discuss our second quarter 2015 results and our outlook for the third quarter and remainder of 2015. After our prepared comments, we’ll host a question-and-answer period. Before we begin this morning, I’d like to remind everyone that our comments today contain forward-looking statements, and we intend to be covered by, and we claim the protection under, the safe harbor provisions for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995. You can identify these statements by forward-looking words such as estimate, may, could, will, believe, expect, would, consider, should, anticipate, project, plan, intend, or similar words.
The company’s actual results could differ materially from any forward-looking statements due to several important factors described in the company’s latest annual report on Form 10-K for the year ended December 31st, 2014, and other recent SEC filings.

Thanks, Tom. Good morning, everyone, and welcome to the O’Reilly Auto Parts second quarter conference call. Participating on the call with me this morning is, of course, Tom McFall, our Chief Financial Officer, and Jeff Shaw, our Executive Vice President of Store Operations and Sales. David O’Reilly, our Executive Chairman, and Greg Johnson, our Executive Vice President of Supply Chain, are also present. It is once again my pleasure to begin our quarterly call by congratulating Team O’Reilly on another record-breaking quarter and an extremely successful first half of 2015. With our team of over 71,000 dedicated team members keenly focused on providing consistently high levels of service to our customers, we generated second-quarter comparable store sales growth of 7.2%. Our year-to-date comparable store sales also increased 7.2% on top of a healthy 5.7% increase last year.
These market share gains are the direct result of our team’s dedication to living the O’Reilly culture of providing outstanding service to our customers, and I cannot thank our team enough for their continued contributions to our company’s long-term success. The 7.2% increase we generated in the second quarter represents the seventh straight quarter we have generated a comparable store sales increase in excess of 5%. We remain steadfast in our commitment to sustainable, profitable growth, demonstrated by our total sales increase of 10.2%, driving a gross margin dollar increase of 11.3% over the second quarter of 2014. The resulting operating profit dollar increase of 14.7%, while solid, is somewhat subdued related to an unusual adverse event that I’d like to take a moment to explain.
As a result of an adverse verdict in a long-term contract dispute with a former service provider, we recorded a $19 million reserve to cover all the potential costs associated with the litigation. This reserve increased our SG&A expense by 93 basis points. Absent the charge, our second quarter operating profit as a percent of sales would have increased 167 basis points to 19.9%, and operating profit dollars would have increased 20.3% over the second quarter of 2014. Our earnings per share of $2.29 for the second quarter is an increase of 20% over last year. While this quarter does represent the 26th consecutive quarter of earnings per share growth in excess of 15%, our EPS would have increased 26% to $2.40 absent this charge. In regards to this event, we’ll continue to aggressively pursue all available options to reduce our ultimate cost.
Okay, now back to our auto parts business. Our comparable store sales increase of 7.2% for both the second quarter and the year strongly exceeded our comparable store sales guidance of 3%-5%. The composition of the comparable store sales growth in the second quarter was also very similar to the first quarter. Both the professional and DIY sides of the business were strong contributors to our comparable store sales growth, with professional being slightly higher. Increases in comparable transaction count and ticket averages contributed equally to the growth. Professional transaction count growth continues to outpace DIY transaction count growth. DIY transaction count growth was a strong contributor to our comparable store sales increase. Average ticket growth on both sides of the business continues to be driven by parts complexity with little to no help from increases in selling price as inflation remains muted.
Our performance for the quarter, as we’ve seen over the past year and a half, was driven by key hard part categories such as brakes, chassis, driveline, and rotating electrical. Through May, the latest data available, miles driven were up 3.4% year-to-date, we feel this increase, driven by relatively low gas prices and improving employment, has been an important factor in our comparable store sales growth. Sales were relatively consistent throughout the quarter, with May being the softest month as cool and wet conditions over much of the central and northern part of the country hurt air conditioning related sales. In recent weeks, summer has taken hold across the country, which should be a positive tailwind for our business, our third quarter is off to a strong start.
Based on moderate, but slightly increasing gas prices and tough comparisons from the third quarter of 2014, we are setting our third quarter comparable store sales guidance at a range of 3%-5%. Based on our strong first half of the year performance, we are increasing our full year comparable store sales guidance to a range of 4%-6%. We are maintaining our full year operating margin guidance at a range of 18.3%-18.7% of sales, which reflects our very strong first half of the year results, but also includes the negative impact of the litigation charge I discussed earlier. We are increasing our full year earnings per share guidance from a range of $8.42-$8.52 to a range of $8.59-$8.69. This updated guidance includes the strong first half results and shares repurchased through yesterday and excludes any potential future share repurchases.
Before I finish up my prepared comments, I would like to again thank our team for these record-breaking second quarter results. We remain very confident in the long-term drivers for demand in our industry, and we believe our team is very well positioned to capitalize on this demand by consistently providing incredible levels of service to our customers each day. Again, congratulations to Team O’Reilly for our very strong second quarter and year-to-date results. With that, I’ll turn the call over to Jeff Shaw. Jeff?
Thanks, Greg, and good morning, everyone. I’d like to begin today by echoing Greg’s comments and congratulating Team O’Reilly on another outstanding quarter. Every day, our focus is to come to work, roll up our sleeves, and out-hustle our competition to earn our customers’ business. While we always have areas where we know we can improve, I couldn’t be more proud of our team’s performance this quarter and year to date. Our industry-leading comparable store sales growth of 7.2% for both the second quarter and the first half of the year is a testament to our team of 71,000-plus team members who are committed to providing consistent top-notch customer service. I’d like to send you a heartfelt thank you.
For the quarter, we grew total revenue 10.2% and total gross margin dollars by 11.3%, proving yet again that our ability to provide exceptional service, a wide product offering at competitive prices, and superior parts availability, allows us to generate sustainable, profitable growth. This growth doesn’t happen without the dedication of our store, distribution center, and office support teams. Including the litigation event that Greg mentioned earlier, we were still able to leverage SG&A 20 basis points in the quarter. I’ll speak to our SG&A results excluding that item, as it is a very unusual event for us and is not indicative of our store operating performance. Excluding the unfortunate event, SG&A leveraged 113 basis points on our strong sales performance, and average SG&A increased 1.4%. This per store increase was higher than expected, primarily driven by more aggressive store staffing and incentive compensation.
On the store staffing front, we’ve been more aggressive putting hours into the stores, that decision has continued to enhance our store-level customer service and is a key driver of our robust market share gains. As we’ve discussed on recent calls, all of our company compensation programs are designed to incentivize our team members to run their business like they own it. As a result, when we drive strong financial results, as we did again this quarter, we spend more payroll dollars at every level of the organization, generate strong leverage. Based on our year-to-date performance and our expectation for the remainder of the year, we’re increasing our expected SG&A growth per store to a range of 1.5%-2%, excluding the litigation event. We feel this level of expense dollars is appropriate given the current environment to maximize our results.
We successfully opened 99 net new stores in the first half of 2015, we continue to be pleased with the performance from our new stores. As we discussed on our last call, we’ll open new stores across our footprint with more significant growth concentrated in Florida, supported by our new distribution center in Lakeland, in California, as we backfill attractive markets not previously penetrated by CSK in the upper Great Lakes, as we freed up capacity across multiple DCs with the opening of our new Chicago DC, in Texas. These markets represented 21 of our 34 openings during the second quarter. Year to date, we’ve strongly exceeded our expected sales volumes, I’d like to take time to thank the members of our supply chain for their outstanding work keeping our stores in stock to meet the robust demand we’ve experienced the past several quarters.
We continually evaluate stocking levels, expediting product with higher than planned sales Filling in on back-ordered product, adjusting routes to handle higher freight volumes, continually modifying our hub, DC city counter, and weekend routes to ensure we have the best availability in each market we serve. The knowledge, dedication, and effectiveness of our supply chain team continues to be a critical component of our success, I cannot thank them enough for their contributions to our company's ongoing success. Looking forward to the third quarter and beyond, we know the key to our success is providing exceptional customer service, as well as the best parts availability in the industry, we strongly feel our team continues to be up to that challenge. I'm very proud and thankful to work with such a great team. Now I'll turn the call over to Tom.
Thanks, Jeff. I'd also like to begin today by thanking Team O'Reilly for another very successful quarter. We're very proud of our record-breaking performance, which is a direct result of our team's dedication and hard work, I'd like to thank each of our store, DC, and support team members for their commitment to making O'Reilly Auto Parts our customer's first choice for auto parts. Now we'll take a closer look at our second quarter results and update our guidance for the remainder of 2015. For the quarter, sales increased to $188 million, comprised of $130 million increase in comp store sales, a $59 million increase in non-comp store sales, a $1 million increase in non-comp non-store sales, a $2 million decrease from closed stores. Based on our strong year-to-date performance, we're raising our full-year total revenue guidance to a range of $7.75 billion-$7.85 billion.
For the quarter, gross margin was 52% of sales, an improvement of 54 basis points over the prior year. This was a little lighter than we expected due to a larger than expected LIFO headwind during the quarter. As we've discussed over the past two years, our success at reducing our acquisition costs over time has exhausted our LIFO reserve, with the result that additional cost decreases create one-time, non-cash headwinds to gross margin as we adjust our existing inventory on hand to the lower cumulative acquisition cost. For the quarter, our LIFO charge was $11 million, which was about double the charge we saw in the second quarter of 2014. Excluding LIFO from both years, gross margin increased 79 basis points. We remain confident in our ability to achieve our full-year gross margin guidance of 51.8%-52.2% of sales.
Our effective tax rate for the quarter was 37.3% of pre-tax income and in line with our expectations. Looking at the full year of 2015, we still expect our tax rate will be approximately 37% of pre-tax income. As is typical in most years, we anticipate our third quarter tax rate to be lower at approximately 36.2% of pre-tax income as we adjust for the expected totaling of certain historical tax periods, and with the fourth quarter returning to a more normal rate of 37.3% of pre-tax income. These estimated rates are subject to the resolution of open tax periods under audit and our success in qualifying for existing job tax credit programs. I'd like to provide some color on our free cash flow results and provide updated guidance for our full-year expectations.
We generated $197 million in free cash flow during the second quarter, which is relatively flat with the prior year. Year to date, we generated $512 million in free cash flow compared to $461 million in the prior year. Based on our strong year-to-date operating income performance, we're raising our full-year free cash flow guidance from a range of $700 million-$750 million to a range of $725 million-$775 million. Inventory per store at the end of the second quarter was $574,000, which is a 2% decrease from the end of 2014. Our ongoing goal is to ensure we grow per store inventory at a lower rate than the comparable store sales growth we generated, and we accomplished that goal through the first half of 2015.
We continue to make great progress on reducing slow-moving and overstock product and replacing it with additional store-level inventory made up of products that are entering higher demand cycles. Part of this year-to-date decrease is timing related, driven by the very strong sales during the first half of the year, and we continue to expect our average inventory per store will increase a little less than 1% for the full year. Our AP to inventory ratio finished the second quarter at 99%, up from 97.7% at the end of the first quarter of this year. The rise in the ratio is related to seasonality and the extremely strong first half sales. During the second half of the year, we believe this ratio will come down slightly, and we continue to expect the year-end AP to inventory ratio will be around 97%.
Capital expenditures for the first six months of 2015 were $187 million, which is a little less than we planned, but we still expect our 2015 CapEx to be within the range of $400 million-$430 million. Moving on to debt. We finished the second quarter with an adjusted debt-to-EBITDA ratio of 1.63 times, down from 1.66 times as of the end of the first quarter, driven by a very strong trailing 12-month operating income performance. We are still well below our targeted ratio of 2 to 2.25 times. However, we continue to believe our stated range is appropriate for our long-term business, and we'll move into this range when the timing is appropriate. During the second quarter, we repurchased two million shares of our stock at an average cost of $221.50 per share.
Year-to-date through yesterday, we repurchased approximately 2.9 million shares of our stock at an average cost of $219.13 per share for a total investment of $630 million. We continue to view our buyback program as an effective means of returning available cash to our shareholders after we take advantage of opportunities to reinvest in our business at a higher rate of return. Currently, we have $649 million remaining under our current authorization and will continue to prudently execute our program with an emphasis on maximizing long-term returns to our shareholders. For the third quarter, we are establishing diluted earnings per share guidance at a range of $2.29-$2.33.
Based on our above-plan results during the first half of the year and additional shares repurchases since our last call, for the full year, we're raising our earnings per share guidance to a range of $8.59-$8.69 per share, representing an increase of $0.17 per share from the annual guidance we provided on our first quarter conference call in April and $0.39 per share from the initial annual guidance we provided at the beginning of the year. As a reminder, our diluted earnings per share guidance for both the third quarter and full year take into account the shares repurchased through yesterday but do not reflect the impact of any potential future share repurchases.
Before I turn the call over to our analysts for questions, I'd like to once again thank the entire O'Reilly team for their continued hard work and dedication to providing consistently high levels of customer service. Congratulations on another record-breaking quarter. This concludes our prepared comments. At this time, I'd like to ask John, the operator, to return to the line, and we'll be happy to answer your questions.
Thank you. We will now begin the 30-minute question-and-answer session. Please limit your questions to one question and one follow-up question. If you have a question, please press star then one on your touch tone phone. If you wish to be removed from the queue, please press the pound sign or the hash key. If you're using a speakerphone, you may need to pick up the handset first before pressing the numbers. Once again, if you do have a question, press star then one on your touch tone phone. Our first question is from Greg Melich from Evercore ISI.
Hi, thanks. I'd love to have a little more insight as to how the different sides of the business performed in the quarter, particularly sort of sequentially, because you had a nice performance both first and second quarter. Did you see a real shift in how DIY versus do it for me played out?
No. Both sides of the business did well in both quarters. We're pleased with both. The professional side is growing a little faster than the DIY side, but both sides of the business are growing well.
On the SG&A, that bumping up for the full year, that shift of 1.5%-2% growth per store, it sounded like that is just solely because of the increased hours and the incentive comp. Was there anything else that's moving that around if you X out the charge?
Those are the key drivers, Greg.
Okay. Lastly, I'll let someone else have another shot. Is there anything that we should think out to next year that you see in the plans that would move the CapEx significantly from the range you have this year?
Go ahead. We would expect to see a similar number. We're going to have more dollars in the San Antonio DC. We haven't set our number for new stores, it'll be in the same neighborhood that we were this year, potentially a few more stores. We'd expect to see a similar number.
Okay, great. Thanks a lot. Good job.
All right. Thanks, Greg.
Our next question is from Seth Basham from Wedbush Securities.
Good morning.
Good morning.
My first question is just on your commentary, Greg, about 3Q. You mentioned it's off to a good start or a strong start, I should say. Any more color on that as it relates to level of trend? Is it in line with the second quarter overall?
Well, we exited the second quarter on a strong sales note, and the trend we were on continued into the third quarter. Something I might mention is that the easiest compares for the third quarter are in the first two months of the third quarter, and then our tougher compares are in the last month. Yeah, we're off to a good start. Business has been solid really all year. We've not seen much variance month to month all year with the exception of, and we mentioned this in our prepared comments, that May, with a lot of rain, a little bit cooler than normal temperatures, our HVAC business didn't do as good as what we would have anticipated, but we feel like we kind of made up for that with the warmer weather that we had in June and July. Business has been good.
Got it. Thank you. One follow-up, in terms of your leverage ratio, still well below your target range. You talked about moving to this range when timing is appropriate. Can you help us better understand when you think that timing is appropriate?
I'll let Tom take that. We have been, over the last few years, more successful
Faster than we anticipated as far as having our suppliers help us with financing inventory and utilizing our vendor financing program. In addition, operating results have been very good, we've generated more cash than we've expected. We continue to look for opportunities to get the best return on that cash. To date, that's been repurchasing shares, and you saw that we picked up the amount of repurchases we had during this quarter, we saw some great opportunities. We'll continue to prudently execute that. To the extent that we have cash on the balance sheet, we're not going to go out and raise debt to have more cash sit on the balance sheet and have a negative carry. When we have opportunities to invest or if we don't have cash on hand, we will look at that point to raise some more debt.
Got it. That's helpful. Congrats on a great quarter, and good luck.
Okay. Thanks, Seth.
Our next question is from Matthew Fassler from Goldman Sachs.
Thanks a lot. Good morning. Congratulations on a terrific quarter.
Thank you.
My first and primary question relates to your comments on parts complexity. If you can just talk about how the change in profile of parts complexity is impacting the DIY business versus the pro business, how it impacts sort of the service needs in the DIY area as well, finally, whether you think that's having an impact on the ticket of the business.
Well, I think it does have an impact on the ticket in the business, I think it will have for the foreseeable future. I think that to the extent that we're talking the parts that are increasing in complexity, which is a big part of our business, absent the things that we carry in our display floors. The types of products that are being used that are electronic-oriented, more sensors, vehicles are in the process now going to direct injection, both diesel and gas. Ignition parts are going to one coil per cylinder as opposed to one coil for the car. Newer vehicles have all these life safety sensors and so forth that add complexity. We see that driving the cost of a repair incrementally up over time. It's hard to forecast what that increase will look like, that'll continue to happen.
All the things I just mentioned tend to make us believe, and I believe make others believe, that the professional business will grow a little better in the coming years than what the DIY business will, simply because this complexity is a challenge for DIY customers. Although, as I've said many times before, and as cars originally started having onboard computers and sensors and so forth, I think that the DIY customer, out of economic necessity, are very adaptable, and there's a lot of companies that are out there providing information and tools to help DIY customers be able to work on cars that have more sensors and more electronics. For that reason, there's many that would bet that the DIY business is going to do pretty well. That's my comment on that.
That's terrific. Just following up on that, putting aside the age of the vehicle fleet, obviously, just thinking about pound for pound, is there a change in the average age of vehicle that's coming in via DIY versus pro or DIFM based on some of the evolving technology that you discussed? Are cars making their way into the DIFM channel or, I guess, staying in the DIFM channel longer, do you think, based on some of the things you just talked about?
I think so. I think that's a trend we'll continue to see. I think the later model vehicles, which are more complex, the 2015s are the most complex. I think that trend has been going on for several years, and that those cars that have the highest levels of complexity tend to stay in the Do It For Me channel longer than what they had years back when DIY customers were able to work on them pretty easily as they came out of warranty.
Great. Thanks so much for that.
Okay. Thanks, Matt.
Our next question is from Dan Wewer from Raymond James.
Thanks. Good morning.
Good morning.
Your do-it-yourself same-store sales are growing faster than the other sector. Yet, if you look at O'Reilly's do-it-yourself revenues per store, it appears to be about $500,000 less compared to AutoZone. When you think about the art of the possible for O'Reilly's do-it-yourself revenues per location, do you think it could be in line with that competitor? If so, what changes would you need to make? I know you've been growing your private label business. You've been expanding your store labor hours to target the do-it-yourselfer, but are there any other initiatives that you would need to make to achieve that kind of productivity?
Well, Dan, as we've said for some time, we view ourselves as having competitors that do better on the DIY side than what we have in the past. I think that some of the things that we've done over the past three or four years to put ourselves in a better position to compete on an equivalent service level perspective with the best retailers in the business, I think is attributed to our growth in the DIY business and will continue to do so. The way I view this is we have this big opportunity to do more DIY business, just as we have this big opportunity to do more on the Do It For Me side. Although we, as you stated, underperform some of our biggest competitors on the DIY side on a per store basis.
The way I look at this is just like going up a staircase. You take it one step at a time.
We've made a lot of positive changes that I feel like are attributing to our DIY growth, and we'll continue to benefit from those changes. As we see opportunities for things that we might be able to do to grow our DIY business better without infringing on our Do It For Me business, we'll continue to do that. I think that there's a lot of reasons that we have an opportunity here, partly based on the team members that we have that are just really good parts people. They know cars, they know parts, they know customer service. I think that our availability of product is unsurpassed in our industry.
I think that as DIY customers who maybe did business with one of our competitors previously and maybe have been coming to our store lately, I think as they realize that we have this fantastic availability model, I think that just bodes well for us in the future. I look for our DIY business to continue to be a significant part of our growth, even with the headwind of parts complexity that I was talking about earlier. As we see things that we need to adjust to make sure we continue to take market share on that side of the business, we'll continue to do so.
A question for Jeff as my follow-up. You talked about putting in more stores into the California market, infilling where CSK was not located. It's been some time since you've given us an update on how the former CSK stores are performing in terms of revenues. As I recall, they were probably over-indexing on the do it yourself channel and underperforming on commercial. Could you give us an update on how those stores are comparing to, say, where they were six or seven years ago?
As Greg mentioned, overall, those stores, that group of stores, continues to perform solidly on both sides of the business. We knew our biggest opportunity was to grow the professional side of the business, we've worked hard on that just from a service level standpoint, strategic hire standpoint. We also are working just as hard on growing the retail side of the business.
Do you think the commercial revenues in those California CSK stores, are they getting to that 40%, 45% of store revenues?
They're not quite there yet.
Okay. All right. Thanks.
Okay. Thank you, Dan.
Our next question is from Mike Baker from Deutsche Bank.
Hi, guys, sorry if this was asked, I dropped off for a minute there. You're clearly taking market share. We know it's because of the company-specific things that you're doing, but what are you seeing from other competitors? There's been some disruption from some of those guys. Are you seeing certain competitors cede more share than they have historically?
It's a store-by-store fight out there every day. This morning, as we're releasing our results, our store managers and installer service specialists are out there trying to take business, and our competitors are doing the exact same thing. We have a lot of strong competitors that do a nice job, and really nothing that we've seen has changed much. We've always had strong competitors, and they've always done a pretty nice job, some better than others. We really haven't seen a change in the tack that our competitors have taken in driving their companies, other than the things that our publicly traded competitors talk about in trying to improve their distribution systems to be more comparable to maybe ours and Genuine Parts, and just trying to solve the availability equation, which is a challenge without the robust distribution network that companies like ours have.
You're clearly taking more market share than you have in the past. I guess in your view, that's more a function of what you guys are doing differently than you have in the past. I think you've always been market share gainers, but it seems like it's accelerating. Do you think that's more a result of what you guys are doing rather than what competitors are doing or not doing?
Yeah. I would attribute our market share gains to just the success of our teams on the street and the work they're putting in to maintaining customer and growing customer relationships on the Do It For Me side, the improvements that we've made on our DIY business the last few years, and really just the day in, day out blocking and tackling on a store-by-store basis and making sure that the service levels we provide are higher than our competitors. At the same time, leveraging our strong distribution network to make sure we have the best availability in the industry.
A lot of that comes from just brute strength and distribution capacity, but a lot of it also comes from the science that we put in to making sure we have the right products in the right locations, and that we do a better job than our competitors in making sure that the parts that we anticipate our customers are going to walk into our stores needing based on the vehicle population in each market are the parts that we have in stock in the stores, in our hubs, and in our distribution centers.
Okay. That's helpful. If I could ask one more real question. How do you think about, and I think this is asked in calls periodically, but any updated thoughts on M&A in the space, anyone out there in terms of acquisitions, either big or small, that you guys would consider?
Well, there's a lot of companies out there that are not publicly traded that are private and do pretty well that would be potential acquisition targets for us. We continue to explore that as we expand geographically, and we even consider some companies sometimes in existing markets, and we do some kind of minor acquisitions ongoing of single stores and things like that. I don't see anything big on the horizon right now that I could speak of, obviously.
Okay. Thanks. Appreciate the color.
Okay. Thank you.
Simeon Gutman from Morgan Stanley.
Thanks, and nice results, guys. Greg, on DIY, a lot of attention on it so far. Do you think there's a pickup in the secular demand, or is all the gains or a lot of the gains you're seeing is mostly market share gains?
I think it's both. I think that we're gaining market share, and I think the DIY business has been pretty good with the economy improving some and gas prices being down, more money in people's pocket, unemployment a little better, miles driven up. I think that it's both a secular demand increase, and I think that we're gaining market share.
The balance that we've long talked about where you were primarily a commercial DIFM house and going too far into the DIY side, there's a fine line that you didn't want to cross. Now you're there. I think there's probably some acceptance among the garages and that you could get bigger in that space. Is there some point you've passed where now you put the pedal to the metal a little bit harder? Are there still some natural resistance points that there's still some product areas, et cetera, that you won't go towards?
Well, what I would say, Simeon, is that we try to do the best we can on both sides of the business, and we treat them somewhat separately from a management standpoint, from the perspective that our promotions are different. Sometimes the product decisions we make, we have to consider both sides. We don't talk to our do-it-for-me customers a lot about our DIY business. Most of the time, our do-it-for-me customers are not really even walking into our stores. We're delivering the parts to them, and they're dealing with an installer service specialist who focuses solely on that business relationship with them, and then also our territory sales managers and our regional field sales managers, store managers, and so forth.
I think we have a lot of business to gain on both sides, and we're less restrictive in the aggressive position that we take on the DIY side now than we ever have been, simply because I think that most shops now realize that customers are going to buy parts from someone if they want to work on their own car. They're either going to buy them from one of our competitors or us, or maybe even on the Internet, and that we're going to be completely supportive of them in driving successful businesses for them and making parts available for them, and that there's just a lot of business that they've got out there to take. To the extent that they provide a service level that's satisfying to their customers and our customers, in effect, that they'll be successful.
I think that most of them are less concerned now than ever about the fact that people can buy parts and do their own work if they want to, but that they can drive a great business by providing these service levels that are necessary to be successful in the service business today.
My brief follow-up for Tom on gross margin. You mentioned ex-LIFO up almost 80 basis points. You said it wasn't up as much as you thought. Was that because of LIFO or even on the 80 basis points you expected to do better? I'm asking because the back-half guidance, I think, implies around 50 basis points, and I'd say 80 basis points, on a FIFO basis, is still quite solid. Just trying to think how to think about gross margin going forward.
The answer to the question is yes. The LIFO headwind higher than we expected drove the slightly below percentage. Maybe we thought we'd be 52.2%, 52.1%, but we've been pretty consistent in our discussion that we'd be in the 51.8%-52.2% range basically quarter after quarter, and we've accomplished that. The additional $5 million headwind over last year was more than we expected.
Okay. Thank you.
Thanks, Simeon.
Our next question is from Michael Lasser from UBS.
Good morning. Thanks a lot for taking my question. It's on the performance for over the last few quarters. There's been a clear step up in the same-store sales. While you've provided some quantitative or qualitative information about the various performance within your sectors, could you give us a little bit greater sense of has that step up been driven more so by the DIY side of the business, or has it been driven more so by the DIFM side of the business, or has both sides of the business stepped up equally?
Well, I'm looking at a sheet here. I can tell you that, for instance, back in 2013, our professional business was growing pretty significantly faster most of the quarters than our DIY business. For the last six quarters or so, they've been much more comparable. I would attribute part of that to just the effect the economy tends to have on the DIY business greater than the do-it-for-me business, just because of the economic condition of what drives someone to maybe work on their own car versus take their car into a shop. Yeah, I would say that here recently with the economy doing a little better, unemployment better, that the DIY business has improved and the commercial business has remained good. The spread between the performance of the DIY and do-it-for-me has closed a little bit over the last couple of years.
Greg, that's a fair point that the economy's probably helped. If we also look at the spread between your performance and your competitors' performance, just on a same-store sales basis, the spread has widened a bit in recent periods. It would suggest that there's probably also something that O'Reilly's doing that's enabling it to gain share and just Observationally, it's occurred at the same time that following the rollout of your loyalty program, you've invested a little more labor in the stores. Can you tie those two factors or others to the performance of your DIY business?
I think those are factors, Michael. No question about it. We work hard here, and we try very hard, and our teams on the street work every single day to show our customers that we want them to walk into our stores on the DIY side. We prove to our professional customers every day that we want to earn their business, and that they're going to be best served to buy parts from us and partner with us. Yeah, it's hard for me to know exactly what all our competitors' initiatives are. I know what they say publicly and what we see on the street.
We, generally speaking, try to stay focused on what we're doing and what we can do better and where our opportunities are, because we have opportunities to improve, and we focus on doing the things that we can do to improve our business and frankly, don't spend a whole lot of time analyzing what our competitors are doing unless there's some significant change that we need to react to, which is really a relatively rare occurrence.
Sure. Then my last question is on capital. That's helpful, Greg. My last question is on capital allocation. Your stock and the valuation of your stock is above where it's been historically. How does that influence both the deployment of excess cash back to shareholders through share purchases, and the potential that you use that as currency to execute your M&A strategy?
Well, what I would tell you, Michael, is historically, it's always proven best for us to deploy our capital into our business, through growing new stores, maintaining our existing store base, and acquiring other chains of stores. When we look at our M&A strategy, there are players out there that we're interested in, but we're an opportunistic buyer, and our success in buying and assimilating chains has a lot to do with buying the right chain at the right price. That's why we're opportunistic. We'll continue to look for those as our number 1 deployment of capital. When we look at buying stock back, we look at what we think the long-term discounted cash flow value is, and set our targets that way.
Okay, that's very helpful. Thank you, Tom and Greg.
Thanks, Mike. Thanks, Michael.
Our next question is from Brian Sponheimer from Gabelli.
Hi, good morning, guys. Great quarter.
Thanks, Brian.
Just thinking about how the quarter progressed, can you talk about what, if any, impact you saw from flooding in Texas, ag markets, or any impact from oil in some of your energy-related markets?
It's hard to measure exactly what impacts businesses. I know you know, generally speaking, the big rains we had down in Texas aren't initially good for business. When things kind of shut down and people can't drive because of water over the roads and stuff like that obviously isn't good for us. In the long run, we feel like it levels back out because of the damage created. Generally, the way the quarter went was April was really good, May was not as good, June was really good. I attribute May's softness or slightly softer results to the heavy rains that we had and just the fact that we've had cooler temperatures, rain, not as good of HVAC business and stuff like that.
Okay. Thank you. Also, just thinking about pricing and any pressures ex oil, how are you guys thinking about inflation versus deflation in some of your non-petroleum related products at this point?
Well, I don't expect deflation, but we've not seen a lot of inflation for some time. We would expect at some point that we might start seeing some inflation in some of the hard parts products, but that's just not been the case for some time. From a pricing standpoint, it's always competitive out there, and we always have competitors who on the do-it-for-me side more than the DIY side tend to try and take business with a lower price for a short period of time to try and change buying habits and stuff like that. That's nothing new. That's been the case forever. Really nothing's changed on the pricing front. It's always competitive, and as I said earlier, we have a lot of really strong and really good competitors who do a lot of different things to try and gain market share.
Some, of course, use price as a means to try and develop a relationship with a do-it-for-me customer, but that's nothing new. I've been doing this 31 years, and that happened the first day I was working in an O’Reilly store, it's nothing new.
Great. Anything on the way as far as wage inflation that could be impactful for you from a cost perspective?
Well, I don't know about the impact effect, of course, we stay in tune with all the discussion about minimum wage changes and stuff like that. As those things, if they come to fruition, we'll be measuring and planning and including those in our forecast for results.
All right. I appreciate the call. Thanks for taking my questions.
Okay. Thank you, Brian.
We have reached our allotted time for questions, and I will now turn the call over to Greg Henslee for closing remarks.
Okay. Thank you, John. We would like to conclude our call today by again thanking Team O’Reilly for another quarter of record-breaking results. We remain very confident in the continued strength of our long-term drivers for demand in the automotive aftermarket and in our team's ability to consistently provide unsurpassed levels of service to our customers. We remain absolutely focused on extending our long history of profitable growth as we build on our very strong performance for the first half of the year. I would like to thank everyone for joining our call today, and we look forward to reporting our 2015 third-quarter results in October. Thank you.
Thank you, ladies and gentlemen. This concludes today's conference. Thank you for participating. You may now disconnect.
